El icono del Ambiente de trabajo BIM

Introducción

El Ambiente de trabajo BIM es un Ambiente de trabajo externo destinado a implementar herramientas completas de Building Information Modeling (BIM) y flujo de trabajo en FreeCAD. Actualmente se parece mucho al Ambiente de trabajo Arch incorporado y ambos probablemente se fusionarán en el futuro. La idea general, sin embargo, es trabajar como un "ambiente de trabajo meta", y reunir en un solo lugar diferentes herramientas de otros ambiente de trabajo que son útiles para el BIM, y crear un flujo de trabajo que sea más conveniente, fácil y amigable tanto para los usuarios experimentados del BIM que vienen de otro software como Revit o ArchiCAD como para los recién llegados. El ambiente de trabajo de la BIM también cuenta con un par de herramientas propias, que son en su mayoría asistentes y herramientas de gestión, ubicadas en el menú Gestión.

The BIM Workbench is based on the built-in Workbench Arch.svg Arch Workbench, and both will probably be merged in the future. The BIM Workbench is a "meta workbench", intended to gather many useful tools from other workbenches in a single place, and create a workflow that is more convenient and user-friendly to both experienced BIM users and beginners. The BIM workbench also features some specific tools of its own, mostly wizards and management tools, located under the Management menu.

See FreeCAD BIM migration guide.

The developers of Draft, Arch and BIM also collaborate with the greater OSArch community, with the ultimate goal of improving building design by using entirely free software.

Instalación

El ambiente de trabajo BIM no está incluido en el paquete predeterminado de FreeCAD, pero puede ser instalado fácilmente a través de la AddonManager.svg Addon Manager. Invóquelo desde Herramientas → Addons Manager. El código del ambiente de trabajo BIM es alojado y desarrollado en github y también puede ser instalado manualmente copiándolo en el directorio MOD de FreeCAD.

Nota

El ambiente de trabajo BIM es un trabajo en progreso, y cambiará a menudo. ¡Asegúrese de actualizarlo regularmente! Si tiene instalado el módulo Python-Git, el ambiente de trabajo de BIM buscará automáticamente las actualizaciones disponibles al inicio, y mostrará un icono en la barra de estado si hay una actualización disponible.

Las herramientas que se enumeran a continuación pueden no estar todas presentes si su versión de FreeCAD no está totalmente actualizada. Sin embargo, el ambiente de trabajo BIM debería funcionar sin problemas en todas las versiones de FreeCAD, sólo eliminará las herramientas no disponibles.

Getting started

BIM welcome screen.png

Upon starting the BIM workbench for the first time, a welcome dialog is shown, giving a quick overview of how the workbench works, and allowing the user to start an in-game tutorial. The welcome dialog is also available from the help menu. When the welcome screen is closed by clicking OK, the BIM setup dialog will be shown, that allows the user to quickly set some of the most common BIM-related preferences of FreeCAD without the need to browse through the full FreeCAD preferences pages.

The BIM project setup tool allows you to quickly setup a BIM project by filling some basic information about your project. You can then, for example, use the different 2D drafting tools to sketch guidelines and baselines, then use the different 3D modeling tools to automatically build 3D BIM objects from them. A line, for example, can become a wall simply by selecting it and pressing the Wall button.

If you are used to another BIM application, check our BIM application compatibility table to get your marks when starting with FreeCAD.

Herramientas

The BIM workbench gather tools from several other FreeCAD workbenches, mainly Draft, Arch and Part, roughly reorganized in logical categories: 2D drafting, 3D modeling, annotation and modification tools. The manage category contains tools that are specific to the BIM workbench.

Additionally, if such addons are installed, tools from Reinforcement (extra reinforcing bar tools), Fasteners (bolts and screws), Flamingo/Dodo (metal structure and piping tools) and Parts Library are automatically included in the BIM workbench.

The BIM workbench also adds a series of items in the status bar of FreeCAD, and a couple of context menu items, accessible by right-clicking in the 3D view or in the tree view.

2D drafting

2D objects are commonly used as drafting aids, or to draw base lines and profiles to build BIM objects on. They can also be used to draw symbols and annotations in your model. Apart from sketches, that use their own coordinate system, 2D objects will be drawn on the current working plane.

  • Sketcher NewSketch.svg Sketch: Creates‎ a new sketch and enters sketch drawing mode. Sketches are advanced 2D objects with constraints support
  • Draft Line.svg Line: Draws a line segment between 2 points
  • Draft Wire.svg Wire: Draws a line made of multiple line segments (polyline)
  • Draft Circle.svg Circle: Draws a circle from center and radius
  • Draft Arc.svg Arc: Draws an arc segment from center, radius, start angle and end angle
  • Draft Arc 3Points.svg Arc 3Points: draws a circular arc segment from three points that are located in the circumference
  • Draft Ellipse.svg Ellipse: Draws an ellipse from two corner points
  • Draft Polygon.svg Polygon: Draws a regular polygon from a center and a radius
  • Draft Rectangle.svg Rectangle: Draws a rectangle from 2 opposite points
  • Draft BSpline.svg BSpline: Draws a B-Spline from a series of points
  • Draft CubicBezCurve.svg Cubic Bezier Curve: draws a Bezier curve of third degree by dragging two points.
  • Draft BezCurve.svg Bezier Curve: Draws a Bezier curve from a series of points
  • Draft Point.svg Point: Inserts a point object

Annotation

Annotations are visual help objects that can be placed inside your model. They can be used to export your model directly to a 2D format like DXF, or reused when creating 2D views of your model with the TechDraw Workbench.

  • Draft Text.svg Text: Draws a multi-line text annotation
  • Draft ShapeString.svg ShapeString: Draws a text line as geometry
  • Draft Dimension.svg Dimension: Draws a linear, angular, radial or diameter dimension
  • Draft Label.svg Label: Places a label with an arrow pointing to a selected element

  • Arch Axis System.svg Axes system: Creates an axes system composed of up to 3 series of axes
  • Arch Grid.svg Grid: Creates a grid-like object to the document
  • Arch SectionPlane.svg Section Plane: Adds a section plane object to the document. Section planes define 2D views such as plans, sections and elevations

Tutorials and Learning

External workbenches

FreeCAD workbenches are easy to program in Python, there are therefore many people developing additional workbenches outside of the FreeCAD main developers.

The external workbenches page has some information and tutorials on some of them, and the FreeCAD Addons project aims at gathering them and making them easily installable from within FreeCAD.

New workbenches are in development, stay tuned!
